"Previous experience with residential string trimmers was that once the mfg supplied product was utilized, you were at the mercy of whatever the hardware store had that would work in your model. When my string trimmer wore down from longtime use, I thought it was joining the junk yard of other lawn care products that hang in my garage. Then I remembered that I bought a lawnmower from your group and the service was great. I looked for, gas/string trimmers, entered my model and voila, there it was. Easy to order, prompt shipping and totals exactly as I ordered"
